    What is causing my car to not even turn over?
    I have tested the battery and replaced the starter. I've tried jumping it off but it still won't turn over. I can't get power when I turn the key to the on position but when I turn the key to the Aux position the radio and door chime will come on. Could this be a ...

    Engine dies while driving.
    My Buick 2003 Regal suddenly dies while driving. The engine stalls then all dash lights are on. Turning the key will start it again. This shows me there was a brief interuption to the electrical system. This happened in the rain so I suspect electrical issues. Once ...

      My first thought is an intermittent rpm signal, that signal comes from crank sensor. I can't rule out an electrical issue like you suggested. Are there any applicable trouble codes? Intermittents can be a pain.

      A. Not sure if this procedure could apply to your vehicle.

      Doing the Passlock theft system relearn:

      1. Verify that the battery is fully charged.

      2. Use your code reader to clear any fault codes.

      3. Turn the ignition switch from the OFF position to the CRANK position, allowing the engine to start/stall.

      4. Release the key, leave the ignition in the ON position for a 11 minutes. Do not continue until at least 11 minutes has passed or the relearn will abort. Going over 11 minutes is OK.

      5. After the 11 minute cycle, turn the key off for 15 seconds.

      6. Repeat Steps 3-5 two more times (3 times total).

      7. After the 3rd cycle, the theft system should synchronize to the new Passlock sensor. It should start and run normally.

      8. Remember that this may get you going but is not a permanent fix. Your permanent fix is likely to replace the Passlock sensor which is the ignition lock cylinder and housing.

      B. If the step A isn't working, see this URL http://www.automd.com/.../

    What is high surge? This is what the code reader says
    When OBD Code Reader applied, it came uo as 940 which translated to high surge. Feel no physical problems except the light coming on.

      This could be caused by a lot of different reasons, have Autozone plug in a scanner to check for any codes, it's free.

      Plug in a code reader and see what fault codes are stored. This cannot be skipped. You can obtain a code reader for about $20 from amazon. Post the code numbers here. If there are no codes, state that you checked and found no codes present.

      sorry, i forgot to add that part

      No codes were found when using code reader at parts store.

      Codes can come and go at different times and if you do not have quick access to a code reader this will be more difficult to diagnose. Buy a code reader. I fully believe that a code will appear soon so check every day. Link to $18 code reader >> http://www.amazon.com/.../ref=sr_1_1

      If you tell me after experiencing this problem for the next 2 weeks that you checked for codes like every other day like 4 times and no codes showed, then I will accept that as a "no codes" situation and I will then advise you accordingly after that.

      With the responses I got from Facebook it seems that the throttle position switch is likely bad. Although it was somewhat unclear whether this could be an intermittent problem. I have already volt tested the tps with car on engine off only. Could the tps act up only while the engine is on for a bit?
      HouseCallAuto
      4/13/2014 HouseCallAuto
      The TPS would definitely set a code and if it were bad you would not miss it on a volt meter sweep. But go ahead and replace it if facebook said it was no good...

    Would a recently replaced ECM (computer) be related to a fuse box needing replacement only 2 mos. after replacement?
    Buick was not starting at all, then after a couple of hrs would start and run normal, then check engine light came on and 2 days later it wouldn't crank, nothing. Took it in to a shop and they stated it needed to clean the throttle body and replace the ECM for ...

      Does anything happen when you turn the ignition key to the on position? Do the dashboard lights come on? Check the main relay inside the fuse box.

      Need more detailed info here, fault code information, this info you may not have so you cannot answer. Also define what "not starting at all" means because it has different interpretations.

    Why does car choke when first cranked.
    When first starting in the morning (cold), it makes a choking noise and wants to die. It doesn't do it when warmed up.

      Are there any codes stored in the ECU? Plug in a scanner and check that first. Could be a faulty sensor, giving incorrect readings.

    Water leaking out of hose next to heater core
    it is a elbow hose,it look like a over flow value
     
    • HouseCallAuto
      4/8/2014 HouseCallAuto
      There are only two liquids that can come from there. Water condensation in a hot climate while the ac is on which is normal, or if the heater core were to leak you would see coolant come out of there. That would mean a bad heater core.

      Replace the instrument cluster. There are several online sources that will repair yours after you ship it to them. Takjes a few days. Removing the cluster is not hard.
